hey man, whats up. i wanted to ask you about a motor i just took out of my
ac unit. it has 4 wires blue, brown, black, and white. i want to use it in
my shop to build a tool someday. im not sure how i should wire it to a
cord. i tried white to nautral and black to black and it wouldnt spin so i
must be doing something wrong or the motor is bad. the brown has me a
little confused, it may need a capasitor in line. not sure. can you give me
some insight on this﻿

I used a commercial 3 step rotary switch on mine to get all three speeds
working. I have a large deck behind the house. I put a couple of vanes on
the front of the blower to spread the flow outward and it works great.﻿

Benhammin Sahstrom With dc a capacitor will hold and discharge
instantaneously but ac will shift phase 90 degrees. so in a since making a
third phase going to a start winding in the motor. but, it is still a good
video!! :)﻿

Thanks for the easy to follow video. My Lennox furnace and its motor are
about 24 years old. I have been maintaining them regularly and oiling the
motor ports as recommended in the manual that came with the furnace. Could
you please comment as to many more years I get out of the motor if properly
maintained. Thanks for your help in the matter.﻿
